Re: 1958 Wizard 5.5hp
58 5.5 was built by Oliver is an Oliver series J .I believe Oliver was in production from about 55 - 60. Oliver bought rights to Chris-Craft outboards about 1955. And made a go of it till about 1960. Scarce as hens teeth. A slight collector attraction due to the Oliver/Chriscraft connection.
Value would vary based on condition/condition/condition.And completeness.
